A two-point Dixon MRI technique was used to quantify the adipose tissue depots in the thigh of elderly women. Women were divided into obese (n=24) and lean (n=17) groups based on BMI, and the lean group was further divided into active (n=9) and sedentary (n=8) based on physical activity level. Thigh composition in lean, sedentary women was found to be similar to that of obese women, while relative adipose tissue depots were elevated relative to active women.
